How to keep tablecells from inheritiing in Swift - swift

Question

I'm trying to generate cells in my table view, each with dynamically allowed buttons on the right-hand side; some with 2 buttons, some with 4 buttons. The problem is, though the table view loads as I'd like, upon scrolling around, the cells end up all having 4 buttons - even the ones that only had two before hand.
What am I doing wrong?
Here is my code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell")! as UITableViewCell
cell.textLabel?.text = self.items[indexPath.row][0]
cell.accessibilityLabel = self.items[indexPath.row][bigSort]
cell.selectionStyle = .None
for x in 0..<4
{
let button = UIButton()
let marginStart = w - tickWidthInCell * 4 - 9 + (tickWidthInCell + 2) * x
let margin = CGFloat(marginStart)
button.frame = CGRectMake(margin, CGFloat(cellHeightMargin), CGFloat(tickWidthInCell), CGFloat(tickHeightInCell))
button.layer.borderColor = GRAY.CGColor
if (self.items[indexPath.row][1] == "Special" && x % 2 != 0)
{
button.backgroundColor = UIColor.clearColor()
button.layer.borderColor = UIColor.clearColor().CGColor
//button.hidden = true
}
else
{
button.addTarget(self, action: #selector(cellButtonClicked), forControlEvents: .TouchUpInside)
button.backgroundColor = UIColor(netHex:0x222222)
button.layer.borderWidth = 1
}
cell.contentView.addSubview(button)
}
return cell
}

Answer 1

It's because tableview reuses the cells you define.
To get control over how the reusing should happen, in your custom UITableViewCell override prepareForReuse. And always reset them the state you want to be, like setting the cell to only have 2 buttons)
Or in cellForRowAtIndexPath you can handle both cases to have either 2 buttons or 4.
(when you are specifying that you want 2 buttons make sure that you hide the other 2)
